Hi Alex,
As I mentioned previously, Windows Messenger makes use of UPnP capabilities to get through a
router/NAT, but Yahoo Messenger uses a few other "tricks". Namely, it will try connecting
you from your contacts' side (that is, if they're not using a router/NAT or firewall as
well), and if that fails, will automatically send your voice conversation through a 'relay'
server. That meaning, your voice gets sent to a central Yahoo server, and then server sends
it to your contact -- and vice versa.
